ACPL-C61L-500E

The ACPL-C61L-500E optocoupler logic gate is a highly efficient and versatile solution with ultra-low current consumption (1.5 mA max) and low input current capability (1.6 mA min for ACPL-061L, 3 mA min for ACPL-C61L, 4 mA min for ACNW261L). Available in various packages, including SO-8 and Stretched SO-8, it features a built-in slew-rate controlled output, a tri-state output with an enable pin (VE), and operates at a high speed of 10 MBd minimum. With a robust Common Mode Rejection (CMR) of 20 kV/μs at VCM = 1000 V and guaranteed performance over a wide temperature range (-40°C to +105°C), the ACPL-C61L-500E is an ideal choice for applications demanding power efficiency, precise signal transmission, and reliable performance in challenging environments.

• Communication Interface: RS485, CANBus, I2C

• Microprocessor System Interfaces

• Digital isolation for A/D, D/A conversion

The ACPL-061L/ACPL-C61L/ACNW261L is an optically coupled optocoupler that combines an AlGaAs light emitting diode and an integrated high gain photo detector addresses the low power need. The optocoupler consumes extremely low power, at maximum 1.5 mA IDD per channel across temperature. The forward current is as low as 1.6 mA to 4 mA and allows direct current drive by most microprocessors.

These optocouplers support both 3.3 V and 5 V supply voltage with guaranteed AC and DC operational parameters from temperature range -40° C to +105° C. The output of the detector IC is a CMOS output. An enable input allows the detector output to be strobed. The internal Faraday shield provides a guaranteed common mode transient immunity specification of 20 kV/μs.

The CMOS output is slew-rate controlled and is designed to allow the rise time and fall time to be controlled over a wide range of the load capacitance.

This unique design provides maximum AC and DC circuit isolation while achieving TTL/CMOS compatibility. These optocouplers are suitable for high speed logic interfacing, while consuming extremely low power.
